4ohm amp into a 2.667 ohm load. Safe?

[jimmyjames77]

On an unrelated topic. I didn't see a reference to 0.5 Ohms in the Sticky SO:

I hooked my amp up today to all my cabs daisy chained together just to try it out. I played it at low volume and it sounded OK. So I thought it should be OK right?

I then turned the master up to 1.5 and smoke came pouring out of the side of my amp.

Do you think it is OK? Maybe just the fan was smoking? I really want my amp to be OK. I don't know what I will do to myself if it is broken. I already have cut myself.

Somebody please tell me it will be OK... PLEASE?

EDIT: Thank You.... for the PMs. I think everything is OK now. I'm going into the backyard and port some cabs now...

That's good stuff.

Quick question. I did a quick search and couldn't find anything.
I'm wanting to run my amp at 4ohms, (it doesn't go to 2 ohm ) into my cabs at a 2.667 ohm load. Is this safe? I know most speakers aren't the exact ohm rating they are rated at anyway. So most loads aren't right anyway. I figured some cabs that "say" they are 4 ohm might be close to 2 ohm anyway...
What do you some peoples with a bit O' Knowledge say?
Jim.

Edit: Yes I do know that ratings are there for a reason. I also know/knew that tube amps are a little different in that regard.

I'd bet a dollar to a donut that you have a 4 ohm speaker/cab in parallel with an 8 ohm speaker/cab. This would give you precisely 2.66667. Depnding on the "tolerance" rating on your amp, you might be okay. But I seriously doubt that the tolerance is that high. You are around 44% under rated on ohms.

Don't worry. You yourself with no previous knowledge can FIX IT in minutes - THANKS TO TEH MIGHTY AND AWESOME POW-ARE OF TEH INTERNUT!



Sure you have enough ammunition? Here's some more for those premium "PA cabs".

Of course that porting cabs part of the post was definately to give you an extra laugh today GB.

I can always use extra ammo.

You are exactly right. I did speak to Peavey and they confirmed that it is OK to do. Still scares me a little though just because.
